hsa-mir-1587: Hsa-mir-1587 is a microRNA that has been identified as less well characterized, with a miRBase ID greater than 1000 [PMC5460954]. It has been found to be secreted through exosomes released by glioma-associated mesenchymal stem cells, and its downstream molecule NCOR1 is suppressed in glioma stem cells, leading to enhanced proliferation, colony formation, and tumor progression [PMC8509502]. Hsa-mir-1587 has been studied in terms of its interactions with proteins and it was found that CASK is a target of hsa-mir-1587 [PMC8509502]. Despite its importance, the interaction of hsa-mir-1587 with proteins has rarely been studied [PMC8509502]. Hsa-mir-1587 can fold into a G-quadruplex structure and is highly expressed in HeLa cells [PMC8509502]. It has also been identified as one of the miRNA binding sites for hsa_circ_0089172 and was found to be differentially expressed compared to the control group in a study on PCOS patients [PMC6579753] [PMC6579986]. Hsa-mir-1587 was one of the miRNAs that were ubiquitously downregulated in comparisons between resting samples from different groups compared to HIV-negative samples [PMC4865051].
